Cadillac Catera Problems

Check Engine Light and/or Erratic Engine Idle

Engine vacuum leaks may develop from the various vacuum hoses causing the engine to idle incorrectly or the Check Engine Light to illuminate. Damaged vacuum lines should be replaced as necessary. Our technicians tell us that rubber vacuum hoses can be used to replace damaged plastic lines if necessary, as long as any connections are vacuum tight.

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Coolant and Oil Leaks

The Catera often experiences oil leaks from the oil cooler and/or valve cover gasket. The thermostat seal and/or the water pump may develop a coolant leak.

I love this car, ride, comfort and handling, and I fix it on my own, I don't trust this car to anybody. I had 4 cateras, and 3 of 4 I got in horrible shape. People never took care before, drove till brakes down, and then it costs a lot to fix at the shop.
